bug#58256: Possible mistake in recent `dired-do-flagged-delete' change

[Stefan Kangas <stefankangas@gmail.com>]

It seems like there might be a mistake in the `dired-do-flagged-delete'
of this commit:

    commit 194d54a929a83fede75d618b104acd1b544feb10

        Fix placement of point in Dired deletion operations

It seems like there is a `dolist' that will always run on the empty
list.  Was perhaps the below the intended change?

If so, I wonder how this code would have worked without that `dolist' so
far, and if that line could just be removed instead?
